Improvement of Structure and Procedure for Raising Acceptance Rate of Sonar Transducer
-
摘要: 针对声呐换能器在研制生产中合格率较低的问题, 采用换能器等效电路理论分析出现这一问题的原因,提出了采用非极化陶瓷片和金属材料热过渡的换能器改进结构及工艺, 试制了改进后的换能器样品并对其进行测试。测试结果表明, 该改进措施可有效提高换能器批量生产中的产品合格率, 为换能器设计和生产提供参考。Abstract: To raise the acceptance rate of sonar transducer in its development and production processes, an equivalent circuit model was built to analyze the factors influencing the acceptance rate. Consequently, a non-polarized piezoelectric ceramic was adopted in the structure of the transducer, and thermal transition of metallic material was applied to the procedure. A prototype of the sonar transducer with the improved structure and procedure was produced and tested. The results indicate that this improvement can raise the acceptance rate of the product.
